摘要： Partial pre-encryption with network-based packet sorting. A video-on-demand (VOD) delivery system for delivering encrypted transport streams to incumbent and overlay set-top boxes utilizes a packet picker/duplicator for sorting selected packets from non-selected packets, duplicating the selected packets, and encrypting one of the pair of duplicated selected packets according to an incumbent encryption scheme. A VOD file server stores the transport stream from the packet picker/duplicator. A network sorter sorts the unencrypted selected packet from the non-selected packets and the encrypted selected packet. The network sorter also sorts the encrypted selected packet from the non-selected packets and encrypts the unencrypted selected packets and the non-selected packets according to an overlay encryption scheme and then sends the transport stream to an overlay set-top box. The network sorter is also responsible for combining the non- selected packets and the incumbent encrypted packets and to send the transport stream to an incumbent set-top box.

摘要： A server in a subscriber television network (100) receives service instances from a headend (102) of the subscriber television network (100). The server is adapted to encrypt according to an encryption scheme and re-transmit service instances to a client-receiver (110). The server reformats the service instance from a first format into a second format the client-receiver can access the service instance.

摘要： Client control may be provided. First, content may be encrypted using an actual key. Then an identifier corresponding to a client device may be received and a transformation may be performed on the actual key and the identifier to produce a transmitted key. The transmitted key and the encrypted content may then be sent to the client device where it may be received. The client device may then receive the identifier corresponding to the client device and perform a reverse transformation on the transmitted key using the identifier to produce the actual key. The content may then be decrypted with the actual key.
摘要翻译：可以提供客户端控制。首先，可以使用实际密钥加密内容。然后，可以接收与客户端设备相对应的标识符，并且可以对实际密钥和标识符执行变换以产生传输的密钥。然后可以将所发送的密钥和加密的内容发送到可以被接收的客户端设备。然后，客户端设备可以接收与客户端设备相对应的标识符，并使用标识符对发送的密钥执行反向变换以产生实际的密钥。然后可以用实际密钥解密内容。

摘要： An information terminal includes a secure microprocessor (204) and secure non-volatile memory (206). Data such as authorization data and other service provider related data for subscription information services are certified as to source, and portions thereof decrypted as necessary by the secure processor according to a service provider key and loaded into secure non-volatile memory. The secure data is loaded by multiple service providers or by subscribers themselves, each service provider being adaptably allocated a number of non-volatile storage cells of predetermined length. In this manner, scarce non-volatile memory resources may be conserved and yet made accessible to multiple information service providers upon demand or as requirements change. Once certified by a trusted entity, several information service providers may individually change or modify the reconfigurable memory of the present invention by remote, addressed communication without the intervention of head-end apparatus.
摘要翻译：信息终端包括安全微处理器（204）和安全非易失性存储器（206）。诸如授权数据和用于订阅信息服务的其他服务提供商相关数据的数据被认证为根据服务提供商密钥的来源和其部分被安全处理器根据需要解密并被加载到安全的非易失性存储器中。安全数据由多个服务提供商或订户本身加载，每个服务提供商被适配地分配许多具有预定长度的非易失性存储单元。以这种方式，可以保存稀少的非易失性存储器资源，并且可以根据需要或随着需求的变化而使多个信息服务提供者可以访问。一旦信任实体认证，几个信息服务提供商可以通过远程的寻址通信单独地改变或修改本发明的可重构存储器，而无需头端设备的介入。

摘要： Encrypting content included in a program or service is disclosed (800), wherein the encrypted content is transmitted from a transmitter to a receiver in a subscriber network. Generally, in one embodiment, the encrypted program or service is packetized (802), and the packets are transmitted to the receiver. When a packet having ciphertext of the encrypted program or service is received (802) at the receiver, the ciphertext of the packet is preferably converted to a different form of ciphertext (804).
